Callee Emulation Test

Callee Emulation Test

The callee emulation test verifies the basic calling services and preliminarily locates a fault.

Prerequisites

  • The OLT and the NMS communicate with each other properly.
  • The NMS is able to discover an online ONT and VoIP service parameters are configured.
  • The user connected to the POTS port that is enabled with callee emulation successfully registers with the softswitch.

Context

The call emulation test verifies the basic calling services during service provisioning, and works with the POTS line test to locate a fault.

There are three types of call emulation tests: caller emulation test, callee emulation test, and automatic emulation test. The call emulation test is irrelevant to protocols for the upstream transmission. That is, it is applicable to SIP and H.248.

After callee emulation is configured on the POTS port, the caller calls the callee and then is put through to the callee automatically.

Impact on the System

  • After callee emulation is enabled on a POTS port, the callee cannot hear the dial tone after offhook but hears mute. After the POTS port is enabled with callee emulation, services carried on the POTS port are interrupted. These services will be recovered after callee emulation is complete.
  • After a POTS port is enabled with callee emulation, if the user of this port is not called by a caller, the user will exit callee emulation in three minutes. Within these three minutes, the VoIP service and other services are interrupted.

Procedure

  1. In the Main Topology, double-click the required OLT in the Physical Root navigation tree; or right-click the required OLT and choose NE Explorer from the shortcut menu.
  2. Choose GPON > GPON Management from the navigation tree.
  3. On the GPON ONU tab page, set the filter criteria or click to display the GPON ONUs.
  4. Select a required record from the ONT list, and then click the Current ONU: UNI Port Info tab in the lower pane.
  5. Select a record from the list whose UNI Type is Pots, right-click, and choose Callee Emulation Test from the shortcut menu.
  6. In the dialog box that is displayed, click Start, as shown in the following figure.

Result

After the callee is called, the phone of the callee is not ringing but emulates the automatic offhook. If the callee hears his/her own voice, callee emulation is successful.
